@Luke, "Cocaine can be used responsibly." ??? Sounds like the trusty words of a cokehead to me. Cocaine makes a person steal, lie, cheat, etc. The marriage might not have bigger problems. If drugs are in the picture, the marriage might have hope if the person can stop. However, a confrontation or intervention might be needed. The first step to any rehabilitation is admittal, since the first sing is denial. Otherwise, the marriage might have bigger problems. oh, btw, you cannot take diluted samples for a test.
